下一个

以下是使用自定义标记的地图示例。我们已经在 Google Charts 配置语法 章节中查看了用于绘制此图表所用的配置。现在，让我们看看整个示例。

配置

我们已使用 图标 配置来自定义标记。

// Set chart options
var options = {
   showTip: true,
   icons: {
      default: {
         normal: 'http://icons.iconarchive.com/icons/icons-land/vista-map-markers/48/Map-Marker-Ball-Azure-icon.png',
         selected: 'http://icons.iconarchive.com/icons/icons-land/vista-map-markers/48/Map-Marker-Ball-Right-Azure-icon.png'
      }
   }	  
};
